Case Study: Pakistan Telecommunication Company Limited achieves a 30% reduction in infrastructure incidents with QualysGuard Vulnerability Management (Qualys)

Pakistan Telecommunication Company Limited Adopts a Comprehensive Approach to Securing IT Assets and Strengthening Its Security Posture

Pakistan Telecommunication Company Limited (PTCL), Pakistan’s largest converged services carrier with more than 20,000 employees, struggled to secure an expanding and complex IT estate. Lacking a unified vulnerability‑management approach, the company relied on manual processes, had limited visibility into network risks, and experienced increasing server crashes and outages that threatened critical business systems.

PTCL implemented QualysGuard Vulnerability Management to discover and map assets, run automated weekly and ad‑hoc scans, and prioritize remediation with a five‑tier severity rating and automated reporting to application teams and management. The solution improved visibility and remediation speed—enabling detection of threats in about 20 minutes—and helped cut server/hardware outages and infrastructure incidents by roughly 20–30%, while allowing the security team to focus on the most critical issues.
